Where can I find a replacement flexible tank for my First 305 ? The original bladder outlet fitting has broken. It fits under the port settee and is approx. 22" x 56". That's about the max size to fit there. I'd previously added a triangular bladder under the V-berth for extra capacity. I've checked Vetus, Plastimo and Imtra. No luck. Ward at Beneteau USA doesn't know the original manufacturer.
